Oxaliplatin-based chemotherapy (FOLFOX [folinic acid, fluorouracil, oxaliplatin] or XELOX [oxaliplatin, capecitabine; also called CAPOX]) for 6 months is the current standard for adjuvant therapy of stage III colon cancer patients with good performance status. However, these regimens are associated with significant toxicities, including myelosuppression, diarrhea, and oxaliplatin-induced, cumulative, dose-dependent neurotoxicity. A reduced duration of adjuvant therapy, which would reduce overall toxicity while maintaining overall clinical efficacy, would be optimal. The goal of the International Duration Evaluation of Adjuvant (IDEA) study was to evaluate the noninferiority of 3-month compared with 6-month adjuvant oxaliplatin-based treatment in stage III colon cancer using a prospectively designed pooled analysis of 6 concurrently conducted phase III randomized trials. Herein, we review the findings of the IDEA study and discuss the optimal duration of oxaliplatin-based adjuvant chemotherapy using patient-based risk factors.
